Au−ZnO Hybrid Nanopyramids and Their Photocatalytic Properties

Abstract

We successfully synthesized Au-ZnO hybrid nanoparticles with a novel hexagonal pyramid-like structure. The growth process of the as-prepared hybrid nanopyramids is clearly discussed. Because of their homogeneous composition and controlled morphology, the Au-ZnO hybrid nanopyramids demonstrate better photocatalytic efficiency than pure ZnO nanocrystals.
